Dota 2 moved to the Source 2 engine well before CS2. The 'New Frontiers' update expanded the map by 40%, increasing the load on CPU and memory. Unlike LoL, Dota 2 uses more complex models and lighting. It benefits significantly from the Vulkan API, which distributes load better across CPU cores, though it still relies heavily on main core performance. For stable performance in chaotic 5v5 fights, 16GB of RAM is highly recommended.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 233 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 230 FPS. At 4K, all settings exceed 122 FPS.
The GeForce RTX 4090 is 521% above the recommended GPU (GeForce GTX 960) for Dota 2. The Core Ultra 7 155H is 286% above the recommended CPU (Core i5-2500K).
The Core Ultra 7 155H determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 4k medium, the Core Ultra 7 155H sets the ceiling at about 171 FPS, while the GeForce RTX 4090 could reach 354 FPS. In this scenario, the CPU limits the GPU potential by 52% (FPS gap: 183 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core Ultra 7 155H is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 23% | CPU Limits GPU 27% | CPU Limits GPU 28% | CPU Limits GPU 31% |
| 1440p (2K QHD) | CPU Limits GPU 29% | CPU Limits GPU 31% | CPU Limits GPU 31% | CPU Limits GPU 34% |
| 4K (Ultra HD) | CPU Limits GPU 48% | CPU Limits GPU 52% | CPU Limits GPU 48% | CPU Limits GPU 52% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Core Ultra 7 155H + GeForce RTX 4090 pairing runs this title with CPU utilization between 15% and 59% and GPU utilization between 39% and 81%. Core Ultra 7 155H keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 53% at 1080p to 61% at 4K, while CPU averages move from 38% to 33%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 66% average at its highest-load preset, while the Core Ultra 7 155H peaks at 42% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 38% and GPU 53%. At 1440p, that shifts to CPU 28% and GPU 58%, and at 4K it reaches CPU 33% and GPU 61%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 36% (23-50%) and GPU 66% (51-81%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Core Ultra 7 155H remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Core Ultra 7 155H and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Core Ultra 7 155H paired with the GeForce RTX 4090 can run Dota 2 smoothly up to 4k achieving around 122 FPS at Ultra quality. Your GPU is 521% above the recommended specs, and your CPU is 286% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Dota 2, upgrading the CPU would have the biggest impact on performance. The Core Ultra 7 155H is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Dota 2 does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Dota 2 requires at minimum a Core 2 Duo E7400 (CPU) and GeForce 8600 GT (GPU) with 4 GB RAM and 60 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 960 with 8 GB RAM. Your Core Ultra 7 155H and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Dota 2 FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
